Avoiding Yada Yada

Most every company talks about their elevator pitch, which is intended to be a brief summation of the business to intrigue one to want to learn more. My question is this: exactly how long are the elevator rides some people are taking? More broadly, in any sort of business interaction, how to you best balance brevity vs. meaty detail?

The Webster’s definition of the phrase “yada yada” is "boring or empty talk often used interjectionally, especially in recounting words regarded as too dull or predictable to be worth repeating." Anyone still recovering from the HIMSS conference can likely recall many conversations where yada yada would have been a very welcomed interjection.
